My guild mates and I are very disappointed with the random chance rewards. With only a 7% chance of a "rare" unit and a 64% chance of a common unit, these prizes are very disappointing.
I used to spend some extra gems on the last day to position myself for a better individual reward. The stats on those rewards weren't very good, but that all had a bonus attached. Now, who cares! No bonus, and probably a unit that doesn't make my army.
The last few hours of this war were pretty boring. No close races for rank, and no one caring about individual placement. This equals less gems spent. Good for us, bad for Gree!
If you're unhappy too, please post your comments here. Maybe Gree will notice and do something. They have been listening a bit better lately.
